A comparison of the symptothermal cycle method using intravaginaltemperature measurement versus conventional temperature measurement - a retrospective cohort study

In conclusion, compared to the standardized manual analysis, an analysis of cycle data performed by women trained in the symptothermal method led to "bio-equivalent" results. However, slight non-significant differences were found in a minority of analyzed cycles and, thus, one can assume that this user-driven analysis might be somewhat less reliable. Noteworthy, the results confirm that the trackle algorithm leads to completely similar results as the standard manual analysis in evaluation of fertile days using the general principles of the symptothermal method. In other words, the trackle algorithm applies these complex rules correctly and reliably.
